Did I get this right?? (Score 1)

Nice plan, except for the fact that the good doctor forgot a little technical detail.IIRC, spraying a salt solution on ice will make the ice melt by lowering the freezing point for the mixture (which is why you use salt in winter on roads). In fact this plan was already advanced once with a different purpose in mind. During WW 2, the British were faced with the problem of providing air escort for the supply convoys traversing the North Atlantic route, and having to do so without aircraft carriers, so someone put forward the idea of cutting ice shelves about 3 by 1 miles in size and spraying them with seawater to make them thicker, to act as floating landing strips. If memory serves me right, there were a couple tests made with the expected disastrous results.
